Define interim payment and state purpose of interim payment.
Interim Payment :
A partial payment given to the contractor monthly for works in
progress or supply in progress under the terms of contract is called as
interim payment.
Note that interim payment is not be considered as final acceptance of
the work upto that level. Powers are given to the engineer to hold the
interim payment under special circumstances.
The interim payment are necessary due to following reasons:
1. In case of large project, the contractor has to invest the large
amount for a longer duration and this is not suitable or possible to
the contractor. Progress of project work may affect due to lack of
funds with the contractor. In such case, the interim payment is made
to the contractor so as to continue the progress of project without
any break.
2. The interim payments also indicate the approximate value of work
done by contractor.
3. If the bills are paid to the contractor at interval, there will be the
check over the progress of the project work. Hence the progress of
the work must be in proportion to the duration of the project.

for demolition of an existing structure so that the particular land can
be developed in any manner. It is different from construction contract
due to following reasons:
i. The contract is given to contractor who quotes higher amount, and
contractor has to pay full amount before demolishing the existing
structure.
ii. The contract must clearly state the contractor is responsible for
making necessary arrangements for cutting off existing service
connections of water supply drainage and electricity
iii. The contractor should be asked

Q.5 b)
Ans.
A person purchases plot measuring 600 sq.m. @ 900 per/m
2
.
He construct building having 200m
2
built up area, cost of
construction being Rs. 700/m
2
. He desires to have net return 6%
on building cost and net return of 5% on land cost, assuming
outgoing 22% of gross income. Suggest suitable rent for property.
Given :
Cost of land = 600  900 = 540000 = 540,000
Cost of building = 200 × 700 = 140000 = 140,000
Step 1 : To find net rent :
Net return,
6% on cost of building =
6
100
 140000
= 8400/-
5% on cost of land =
5
100
 540000
= 27000/-
Gross rent = Net rent + out going
 Net rent = Net return/annum
Out going = 0.22 GR
Net rent = 8400 + 27000
= 35400/-
Step 2 : To find gross rent :
Gross rent = 35400 + 0.22 GR
0.78 GR = 35400
GR = 45384.61/year
Step 3 : To find gross rent per month :
 Gross rent per month = 45384.61/12
= 3782.05
= 3782/-

Q. 5 c)
Ans.
Explain:
i. Market value
ii. Book value
iii. Scrap value
iv. Salvage value
i. Market value: It is the value or amount of a property, which
may be obtained at any time from the open market.
The market value changes from time to time for various
miscellaneous reasons such as changes in industry, changes in
fashions, means of transport, cost of materials and labour etc.
.
ii. Book value: It is the value or amount mentioned in the account
book at the time of purchase and can be obtained on deduction
done by depreciation.
The book value of a property at a particular year is the original
cost minus the amount of depreciation allowed per year and will
be gradually reduced year to year and at the end of the utility
period of the property, the book value will be only scrap value.
iii. Scrap value: It is the value of dismantled materials of a
property at the end of its utility period. Scrap value is the value
of dismantled material. The dismantled materials such as steel,
bricks, timber etc. will fetch a certain amount which is the scrap
value of building. The amount of scrap value may be about 10%
of its total cost of construction.
v. Salvage value: It is the value at the end of utility period without
being dismantled. Salvage value is significant as it allows
calculating the depreciation.

Explain in brief legal aspect of specification.
i. Specification of various items becomes the important documents
as per as legal aspect like contract and agreements are concerned.
Hence the drawing and specifications are two important contract
documents considered as a legal documents.
ii. The tender documents and agreements towards legal aspect are
incomplete and invalid without specifications.
iii. Specifications have more legal strength and hence most of the
contract state that in case of discrepancy between the drawings and
specifications, the specification act as a legal proof.
iv. In case of disputes between the owner and the contractor,
specifications act as a useful legal documents to solve the problem
in between two party.
Enlist types of specifications and explain any one in brief.
Following are the various types of specifications :
a. Brief specification
b. Detailed specification
c. Standard specification
d. Manufacturers specification
a. Brief specification :
i. The general specification used for estimating the project are the
brief specifications.

 The specification in which detailed information of the various
quantities of materials, procedure of workmanship to be adopted,
nature and class of work is mentioned.
 Hence detailed specification form a part of contract document.
 Detailed specification for a particular item specify the following
information :
i. Qualities of material
ii. Quantities of material and their proportions
iii. Method of doing work or procedure of work.
iv. Test required on the constructional material or on the
finished items.
v. Type of equipments and machinery used.
vi. Special tools and plants used.
vii.Method of operations of special tools and plants.
In short, without the detailed specification for a particular item, the
tender documents and contract are incomplete and considered as
invalid.
OR
3. Standard specification :
 Detailed specifications for various works are drawn up by an
engineering department and these specifications are printed and
used as a standard specification. Hence most of the items in works
are made to standardized specifications.
 Standard specification play a vital role that it work as guide and
also refer in the specification part of a tender documents and thus
avoids writing lengthy specification.
 Note that whenever the standard specifications are accepted for a
particular work, then it should be observed carefully and suitable
modifications or necessary corrections are made accordingly.
 Standard specifications must be periodically revised so as to
include some changes in techniques.
 Specifications of items such as stone work, brickwork, plastering,
pointing, excavation, earthwork concreting etc. becomes common
in writing particulars of such items and hence it is not required to
write such common specification again and again.
 Standard specifications are mostly referred because it saves the
time and there is no possibility of doing mistakes.
